Cacopsylla bibari , PARK, 1996: 271.

Psylla (Hepatopsylla) quelparticola KWON, 1983: 64, syn. nov. Cacopsylla quelparticola , PARK, 1996: 272.

Cacopsylla SP. 1, HAYASHI & MIYATAKE, 2012: 39.

Material examined. South Korea (JJ, JN) ( NHMB, SNU).

Host plant. Pittosporum tobira (Thunb.) W.T. Aiton (Pittosporaceae) , confirmed by the presence of immatures.

Comments. Kwon (1983) described both Cacopsylla quelparticola and C. bibari based on a single male each from Jeju Island. The major difference between the two is, according to Kwon (1983), the spinule free stripes on the forewing which are ‘apparently broad’ in the former and ‘prominent but relatively narrower’ in the latter. We collected large series of specimens in several localities on Jeju Island and in the South of the Peninsula, along with Cacopsylla tobirae on Pittosporum tobirae (Pittosporaceae) , which suggest that these differences are within the range of intraspecific variation. For this reason, we synonymise the two taxa. As both species have been described in the same publication we chose Psylla bibari as senior name as it is more euphonious and, thus, complies better with recommendation 25C of the International Commission on Zoological Nomenclature (1999). Cacopsylla sp. 1 by Hayashi & Miyatake (2012) from Japan, collected on Pittosporum tobirae , is referrable to C. bibari .
